Keyword Protected Door

Hey guys,
I wanted to make a keyword-protected door. The first keyword should emit redstone at the backside… the second on the right. It works perfectly but there is one thing that I couldn't do:
My Code:

correctpass = ("password1")
correctpass2 = ("password2")
pass = read()
if correctpass == pass then
  redstone.setOutput("back",true)
  print("Keyword correct!")
  sleep(3)
  redstone.setOutput("back",false)
  os.shutdown()
  end
if correctpass2 == pass then
  redstone.setOutput("right",true)
  print("Put a senseless sentence here, which is not sentence one")
  sleep(3)
  redstone.setOutput("right",false)
  os.shutdown()
else
  print("Invalid Keyword")
  sleep(3)
  os.shutdown()
  end

As I sad before: works perfectly.

Now I want to something that says:
- Put in keyword here:
or:
- Keyword?

I tried it out yesterday and I don't know how I did it exactly.
So the program ran. It even emitted redstone but it said Keyword first when I had put the Keyword in. It looked like this:

password2
Keyword? Door opening…

Can you help me?
Thanks.

What is your problem exactly?

I want that the computer says something like "Write password here…" when I start him.
Momentary when you start the computer it says nothing and you have to write the keyword.

print("Password: ")
term.setCursorPos(11,1)
pass=read() 

Done…

Do I have to go on with my own code after this?

This is already an implementation to your code.

You may need this:

correctpass = ("password1")
correctpass2 = ("password2")
pass = read()
elseif correctpass == pass then
  redstone.setOutput("back",true)
  print("Keyword correct!")
  sleep(3)
  redstone.setOutput("back",false)
  os.shutdown()
elseif correctpass2 == pass then
  redstone.setOutput("right",true)
  print("Put a senseless sentence here, which is not sentence one")
  sleep(3)
  redstone.setOutput("right",false)
  os.shutdown()
else
  print("Invalid Keyword")
  sleep(3)
  os.shutdown()
end

To help simply it a bit.
